I'm trying to move a script from invoking lots of sed and awk to bash builtins and I'm stumped on something I'm sure is simple.
Is there a tr equivalent to the following? sed 's/[^[:alnum:]]//g'
Try
tr -c [:alnum:] ....
-c --complement

Almost, but that got me on the right track. I needed:
tr --delete --complement [:alnum:]
and presto! I knew it had to be something really, really silly I was overlooking. Something such as, for example, the very first switch in the manpage.
Thanks!
